Abstract

There is provided a biometric authentication method using a portable electronic device. The method includes identifying a gesture of a user to be authenticated through a gesture recognition unit of the portable electronic device and acquiring biometric information of the user through an information input unit of the portable electronic device. The method further includes comparing the identified gesture and the acquired biometric information with an authentication information stored in an information storage unit to perform the biometric authentication of the user, and outputting a result of the biometric authentication.

Claims

1. A non-transitory computer-readable storage medium including computer-executable instructions, which cause, when executed by a processor, the processor to perform a method for biometric authentication using a portable electronic device, the method comprising:

identifying a gesture of a user to be authenticated;

acquiring biometric information of the user;

comparing the identified gesture and the acquired biometric information with pre-registered authentication information to perform the biometric authentication of the user; and

outputting a result of the biometric authentication.

2. The non-transitory computer-readable storage medium of claim 1, wherein the gesture is performed with the portable electronic device and the gesture is determined by at least one of a motion of the user performed with the portable electronic device, a positional angle of the portable electronic device, and a touch operation on the portable electronic device for a predetermined time period.

3. The non-transitory computer-readable storage medium of claim 2, wherein the motion and the positional angle are measured by an inertial sensor equipped in the portable electronic device.

4. The non-transitory computer-readable storage medium of claim 2, wherein the positional angle is measured by an imaging device integrally equipped in the portable electronic device.

5. The non-transitory computer-readable storage medium of claim 4, wherein the positional angle is obtained by measuring a position or a gradient of an object in an image captured by the imaging device.

6. The non-transitory computer-readable storage medium of claim 1, wherein said comparing the identified gesture and the acquired biometric information comprises:

comparing the identified gesture with registered gesture information included in the pre-registered authentication information and calculating a gesture similarity therebetween;

comparing the acquired biometric information with registered biometric information included in the pre-registered authentication information and calculating a biometric similarity therebetween;

calculating a combined similarity based on the gesture similarity and the biometric similarity; and

determining the result of the biometric authentication as success or failure based on a result of comparing the combined similarity with a threshold for the combined similarity included in the pre-registered authentication information.

7. The non-transitory computer-readable storage medium of claim 1, wherein said comparing the identified gesture and the acquired biometric information comprises:

extracting gesture feature information from the identified gesture;

extracting biometric feature information from the acquired biometric information;

comparing the gesture feature information and the biometric feature information with the pre-registered authentication information to calculate a feature information similarity; and

determining the result of the biometric authentication as success or failure based on a result of comparing the feature information similarity with a similarity threshold included in the pre-registered authentication information.

8. The non-transitory computer-readable storage medium of claim 1, wherein said comparing the identified gesture and the acquired biometric information is carried out upon when the identified gesture and the acquired biometric information are inputted simultaneously.

9. A biometric authentication method using a portable electronic device, the method comprising:

identifying a gesture of a user to be authenticated through a gesture recognition unit of the portable electronic device;

acquiring biometric information of the user through an information input unit of the portable electronic device;

comparing the identified gesture and the acquired biometric information with an authentication information stored in an information storage unit to perform the biometric authentication of the user; and

outputting a result of the biometric authentication.

10. The method of claim 9, wherein the gesture is performed with the portable electronic device and the gesture is determined by at least one of a motion of the user performed with the portable electronic device, a positional angle of the portable electronic device, and a touch operation on the portable electronic device for a predetermined time period.

11. The method of claim 10, wherein the gesture recognition unit is an inertial sensor;

and

the motion and the positional angle are measured by the inertial sensor equipped in the portable electronic device.

12. The method of claim 10, wherein the gesture recognition unit is an imaging device integrally equipped in the portable electronic device;

and

wherein the positional angle is measured by the imaging device.

13. The method of claim 12, wherein the positional angle is obtained by measuring a position or a gradient of an object in an image captured by the imaging device.

14. The method of claim 9, wherein said comparing the identified gesture and the acquired biometric information comprises:

comparing the identified gesture with registered gesture information included in the authentication information and calculating a gesture similarity therebetween;

comparing the acquired biometric information with registered biometric information included in the authentication information and calculating a biometric similarity therebetween;

calculating a combined similarity based on the gesture similarity and the biometric similarity; and

determining the result of the biometric authentication as success or failure based on a result of comparing the combined similarity with a threshold for the combined similarity included in the authentication information.

15. The method of claim 9, wherein said comparing the identified gesture and the acquired biometric information comprises:

extracting gesture feature information from the identified gesture;

extracting biometric feature information from the acquired biometric information;

comparing the gesture feature information and the biometric feature information with the authentication information to calculate a feature information similarity; and

determining the result of the biometric authentication as success or failure based on a result of comparing the feature information similarity with a similarity threshold included in the authentication information.

16. The method of claim 9, wherein said comparing the identified gesture and the acquired biometric information is carried out upon when the identified gesture and the acquired biometric information are inputted simultaneously.

17. A biometric authentication apparatus comprising:

a gesture recognition unit configured to identify a gesture of a user to be authenticated;

an information input unit configured to receive biometric information of the user;

an information storage unit in which authentication information for use in the biometric authentication is registered; and

a control unit,

wherein the control unit is configured to;

compare the identified gesture and the biometric information with the authentication information to perform the biometric authentication of the user, and

output a result of the biometric authentication.

18. The apparatus of claim 17, wherein the control unit is configured to:

compare the identified gesture with registered gesture information included in the authentication information and calculate a gesture similarity therebetween;

compare the biometric information with registered biometric information included in the authentication information and calculate a biometric similarity therebetween;

calculate a combined similarity based on the gesture similarity and the biometric similarity; and

determine the result of the biometric authentication as success or failure based on a result of comparing the combined similarity with a threshold for the combined similarity included in the authentication information.

19. The apparatus of claim 17, wherein the control unit is configured to:

extract gesture feature information from the identified gesture;
